    A new blow to the solar-energy supply chain

    Tongwei has halted output at a polysilicon factory in China’s southwestern Sichuan province because of flooding, the latest blow to the solar supply chain that has seen rare cost increases this summer due to disruptions.

    Tongwei, the world’s third largest polysilicon producer last year, said it isn’t clear when production will resume, and didn’t say whether its plant sustained damage. The facility can produce 20 000t of polysilicon a year, which would be about 4% of global production last year, according to data compiled by BloombergNEF.

    The move could further pinch the solar supply chain, which is in the midst of a rare period of rising costs after a 19 July explosion at a polysilicon plant in Xinjiang cut global supply of the material used as the building block for solar power globally.

    A short-term price rise driven by this event is possible. But further price rise may lead to project delays

    “A short-term price rise driven by this event is possible,” said Yali Jiang, an analyst with BloombergNEF. “But further price rise may lead to project delays considering the already high upstream prices.”

    Prices for the material have surged by 56% since 15 July, according to PVInsights. Wafer and cell makers have since boosted prices to pass along some of the increased cost. Any further impact on prices may depend on the duration of the outage.

    China has been battered by severe floods since June, affecting more than 63 million people, according to a posting on the ministry of emergency management’s website.  — (c) 2020 Bloomberg LP
